  • Patent number: 10119429
    Abstract: A linear variable differential transformer (LVDT) for monitoring engine valve position is disclosed. The system includes a valve guide having an elongated recess through it. The engine valve has a valve head and a valve stem with two adjacent materials having different magnetic properties meeting at an interface. The valve stem fits and moves linearly within the valve guide, and the valve head closes an engine combustion chamber. It also includes monitoring coils within the valve guide that create a signal related to the position of the interface within the valve guide. An engine control unit (ECU) is coupled to the monitoring coils and receives and analyzes the signal from the monitoring coils to determine operation of the valve.

  • Patent number: 10082050
    Abstract: An anti-rotation guide for a lifter in an overhead valve valvetrain. The anti-rotation guide includes a plug having two lobes connected through a neck region. A first lobe of the plug is held within a bore in the lifter. The bore forms an opening at the edge of the lifter through which the neck of the plug emerges. The bore in the lifter accommodates a first lobe of the plug that is wider than the opening in the edge of the lifter, whereby the plug is shaped to prevent its slipping from the lifter through the opening. The lifter reciprocates in a first bore in the cylinder head. The second lobe of the plug extends outward from the lifter into a second bore formed in the cylinder head and adjoining the first bore. The second lobe reciprocates in the second bore and limits rotation of the lifter.

  • Patent number: 9702279
    Abstract: A system for controlling variable valve actuation in an automobile engine. A first cam has a first lift profile and a second cam has a second lift profile. A rocker arm assembly engages the cams having a first arm for riding on the first cam, and a second arm for riding on the second cam. The second arm has an activatable latch capable of securing the second arm to the first arm when latched. When the first arm is secured to the second arm, the rocker arm assembly achieves a first lift profile and when the first arm is not secured to the second arm, the rocker arm assembly achieves a second lift profile. A non-contact sensor mounted adjacent the rocker arm assembly is adapted to monitor and create data indicative of whether the first arm is secured to the second arm.

  • Patent number: 9554214
    Abstract: A microphone includes a base, a micro electro mechanical system (MEMS) device disposed on the base, and a front end processing apparatus disposed on the base and coupled to the MEMS device, the front end processing apparatus being configured to convert analog signals received from the MEMS device into digital signals. The microphone also includes a DSP apparatus, the DSP apparatus being a digital programmed device with a computer memory, the DSP apparatus configured to process the digital signals received from the front end processing apparatus. The MEMS device, the front end processing apparatus, and DSP apparatus are enclosed within a single microphone enclosure or assembly. During operation the DSP apparatus generates DSP noise. The DSP apparatus includes a noise reduction structure that substantially prevents the DSP noise from reaching or interfering with the operation of the MEMS device or the front end processing apparatus.
